no format it says( Pro Evolution Soccer 2007 [USA][UMDFull][English][PSP) and has loads of files in it no rar or zip files just looks like you are exploreing the disk.
i converted game ok put it on psp it starts to load then black screen and game could not be started ( 80020321 ) my f/w is 3.10 i have enabled no umd changed clock speeds and still no joy please can someone help.
disable the "NO UMD" and try it again with a umd disc in the drive.
the error code ( 80020321 ) means you have no umd disc in your psp.
you still need a disc to play back up's, unless the game will work with the no umd option.
